The HOBO MX1102A CO2/Temp/RH data logger uses integrated sensors to record carbon dioxide (CO2), temperature, and/or relative humidity (RH) in indoor environments. This Bluetooth Low Energy (BLE)-enabled logger is designed for wireless communication with an iOS or Android mobile device.

Using the HOBOmobile app, you can easily configure the logger, read it out, view data on your phone or tablet, export the data, or automatically upload the data to HOBOlink’s free cloud storage, for further analysis. The logger can calculate minimum, maximum, average, and standard deviation statistics and can be configured to trip audible or visual alarms at thresholds you specify. The MX1102A supports burst logging, in which data are logged at a different interval when sensor readings are above or below certain limits. This compact data logger also has a built-in LCD screen to display the current CO2, temperature, relative humidity, logging status, battery use, memory consumption, and more.

You can download the HOBOmobile app for free for Android devices here and for iOS devices here.

The Hobo MX Gateway (purchased separately) can be used to aggregate the data from up to 100 Hobo MX data loggers directly to a PC via Ethernet or WiFi communications.
